A method for producing methacrylic acid esters and a device for making it |
| abstract |
The invention relates to a method and apparatusnfor the production of methacrylic acid esters.nMethacrylic acid estersnaccording to the invention are produced from methacrylamide sulfate,nalcohol and water fornsulfuric acid and inhibitornpolymerization in an apparatus comprisingnfrom 1 to 6 reactors and a diameter rationto 0.12 to 0.32. To the reactionnthe mixture is added hydrophobically extractionnin 0.5 to 3-fold volumento the actual reaction mixture,nwherein the system is agitated with a stirrer with 5nup to 10 blades placed one above the othernwithout overlapping the twonphases. The organic phase temperature is maintainednat 70-110 ° C, aqueous temperaturenphase at 80 to 150 ° C and individuallynthe phases are continuously removed. |
